Abstract

본 발명은 아시아 위성 방송신호와 일본 위성 방송 신호 및 무궁화 위성 방송 신호를 모두 수신할 수 있는 보다 개선된 위성 방송 수신장치에 관한 것이다.The present invention relates to an improved satellite broadcast receiver capable of receiving both Asian satellite broadcast signals, Japanese satellite broadcast signals, and Mugunghwa satellite broadcast signals.

본 발명은 3개의 위성 방송신호를 수신하기 위하여 3개의 위성 방송 수신용 안테나와 3개의 저잡음 주파수 변환기 및 3개의 위성 방송 수신기(SVR)을 필요로 하게되는 문제점을 해결하기 위하여 1개의 위성 방송 수신기용 안테나와 2개의 저잡음 주파수 변환기 및 1개의 위성 방송 수신기(SVR)로 3개의 위성 방송 신호를 수신할 수 있는 위성 방송 수신 장치를 제공하는데 그 목적이 있다.The present invention relates to one satellite broadcast receiver to solve the problem of requiring three satellite broadcast reception antennas, three low noise frequency converters and three satellite broadcast receivers (SVRs) to receive three satellite broadcast signals. An object of the present invention is to provide a satellite broadcast receiving apparatus capable of receiving three satellite broadcast signals with an antenna, two low noise frequency converters, and one satellite broadcast receiver (SVR).

본 발명은 위성 방송신호를 수신하는 안테나와, 상기 안테나에 수신된 제1위성 방송 신호를 처리하는 제1저잡음 주파수 변환기와, 상기 안테나에 수신된 제2,3위성 방송 신호를 처리하는 제2저잡음 주파수 변환기와, 상기 제1,2저잡음 주파수 변환기의 출력신호를 선택하는 스위치와, 상기 스위치에 연결되는 위성 수신기(SVR)을 포함하는 것을 특징으로 하고 1개의 접시형 안테나와 2개의 저잡음 주파수 변환기 및 1개의 위성 수신기(SVR)를 이용하여 3개의 위성 방송신호를 모두 수신하는 위성 방송 수신장치의 비용을 줄일 수 있는 효과가 있게 된다.The present invention provides an antenna for receiving satellite broadcast signals, a first low noise frequency converter for processing a first satellite broadcast signal received at the antenna, and a second low noise for processing second and third satellite broadcast signals received at the antenna. A frequency converter, a switch for selecting an output signal of said first and second low noise frequency converters, and a satellite receiver (SVR) connected to said switch, said one dish antenna and two low noise frequency converters; By using one satellite receiver (SVR), it is possible to reduce the cost of the satellite broadcast receiver for receiving all three satellite broadcast signals.
